For everyday snapshots of your kids, your dog, and your road trip to see the world’s largest ball of twine, your Mac comes with iPhoto, a simple way to organize and edit your photos. But pro shutterbugs and photography enthusiasts need far more serious tools to manage ever-growing libraries of tens of thousands of images. Adobe’s latest iteration of Lightroom aims to answer that call with pro-level organization and photo management, as well as robust editing tools for perfecting your shots.
